Yuriko, a life insurance representative, is a top performer, using her feminine charm to secure clients. One day, she encounters Yuko, who dominates her husband, and presents a contract condition: to humiliate Yuriko and use the footage to blackmail her. However, Yuriko retaliates by raping Yuko, tormenting her as she begs for mercy, and ultimately exacting her revenge by penetrating Yuko with a strap-on.
